"I’m a kindergarten teacher. I spend 8 hours on my feet, chasing 5-year-olds and squatting all day. By 6pm my knees were throbbing and I’d crash on the couch. I started using Ember each night while watching TV. Within a week I had enough energy to cook dinner. Two weeks later I was playing with my own kids again. It’s been 2 months and I honestly don’t know how I lived without it."

"Got Ember for my right knee after my doctor told me to avoid surgery for as long as possible, and I’m honestly surprised how much relief it gives. The infrared heat soothes my knee fast, especially after a long day. I use it most nights for about 15–20 minutes, and my knee feels so much better. It’s easy to use, comfortable to wear, and does exactly what it says it will."

"My boyfriend works construction as a roofer. He tells me every night he doesn't know how long he can keep going up and down on those ladders because his knee is pretty much bone on bone. So I bought this for him hoping that it would give him some relief, and boy did it ever! He doesn't complain nearly as much as he did before, and we've even started taking our dog for walks after he's done work."

"I play semi-pro basketball. I used to limp to the locker room after games. I bought an Ember after seeing it help my teammates and started using it on the bench post-game. Now I'm walking out pain-free, and I make sure I bring it to every game."

"I’m a nurse, so I’m on my feet 12+ hours a shift, and my knees were killing me every single night. I picked up this about 4 days ago and I’ve used it every night since. It really helps take the edge off that deep, sore ache. I can tell a difference in how less stiff and painful my knees feel in the morning. This is 100% worth it."

Sound Like You?

  • You groan when getting up from the couch

  • Stairs make you wince or avoid them entirely  

  • You feel like you're "too young to feel this old"

  • Playing with grandkids means paying for it later

  • You've tried ice, heat, pills, but nothing has worked long-term

  • You're worried it's only going to get worse

  • Simple movements that used to be easy... aren't anymore

  • You're tired of feeling limited by your own body

Recommended By Healthcare Professionals

Dr. Wendy Sampson, MD

Sports Medicine Physician, Hawthorne Athletic Clinic

In sports medicine, we focus on keeping patients active between appointments. Ember's combination of infrared heat, red light therapy, and vibration addresses the main things we target in practice. Primarily, circulation and muscle tension around the joint. For patients committed to daily use, Ember is a practical at-home option.
Dr. Jennifer Hollis, DPT

Doctor of Physical Therapy, Summit Ridge Rehabilitation Center

Physical therapists use infrared heat, red light therapy, and vibration together because they address both the joint and the surrounding soft tissue simultaneously. Ember makes that approach practical for daily home use, which is where consistency actually matters. I recommend it to patients who want to support their knee health between sessions.
Dr. Michael Kehoe, MD

Orthopedic Surgeon, St. Joseph's Hospital for Orthopedics

Many of my patients are managing knee discomfort while weighing whether more invasive intervention is necessary. For those patients, consistent at-home therapy makes a meaningful difference. Ember's multi-modal strategy of red light, compression, vibration, and infrared heat is consistent with what we see working in clinical rehabilitation.
Dr. Priya Natarajan, MD

Occupational Medicine Physician, Brookfield Medical Institute

Nearly every patient whose job keeps them on their feet deals with cumulative knee wear, and standard interventions are often impractical for people with demanding schedules. Ember's technology supports daily comfort in a format that actually fits into a working person's day.
Dr. David Olia, MD

Geriatric Medicine Physician, St. Jude Medical Center

Knee discomfort is one of the most common concerns I hear from older adults, and it directly affects their independence and quality of life. Ember's combination of heat, vibration, and compression is practical for daily use in a way that more complex interventions often aren't. Additionally, the inclusion of high-quality red light therapy in this device is a rare find in the consumer market. Ember is a consistent at-home option that fits naturally into a broader wellness routine.

Here's Exactly Who Ember Is Built For


Ember is built for people who refuse to accept that living with knee pain is just how it's going to be.

The nurse who needs her legs for the next shift. The grandfather who isn't done playing with his grandkids. The contractor who can't afford to slow down.

If you're still fighting for the life you want — Ember was built for you.


Ember Works Best For:

✅ People with everyday knee discomfort from activity, age, or occupational wear

✅ People who want help managing daily knee pain without having to rely on pills, creams, or patches

✅ Anyone who has tried single-solution products like heating pads, ice packs, or TENS units without lasting results

✅ People who want a non-invasive option they can use at home

✅ Anyone who spends long hours on their feet — construction, nursing, retail, teaching, warehousing

✅ Active adults and seniors managing stiffness and reduced mobility

✅ Athletes and weekend warriors managing soreness and recovery


Ember Is Not The Right Fit If:

❌ You have an active infection, open wound, or severe swelling in the knee area

❌ You have an implanted electronic device such as a pacemaker

❌ You are pregnant

❌ You are looking for a cure for a diagnosed medical condition — Ember is a wellness device, not a medical device

❌ You expect results without consistent daily use — Ember works best when used regularly


If you have a diagnosed knee condition or are post-surgery, please consult your physician before use.

Many of our customers use Ember as a complement to their existing care plan — but that conversation should happen with your doctor first.


If Ember sounds right for you, here's exactly what to expect from your very first session.


What Happens In Your First 15 Minutes

Minutes 1-5:

The first thing most people notice is the warmth.

NOT surface warmth. You know the kind that only sits on your skin for a few minutes and then fades?

Ember goes deeper. It takes about 60-90 seconds to feel it settle into the joint.

The vibration starts working on the muscles and tension surrounding the joint.

Compression holds everything comfortably in place.

And the moment you press start, all 14 red light diodes activate, working deep at the cellular level.

Minutes 5-10:

The heat, red light, compression, and vibration work together to help your knee feel more relaxed and supported.

Most people notice the tension starting to ease.

Minutes 10-15:

Your session is almost done.

Many people finish feeling looser, more comfortable, and ready to get back to their day.

After 15 minutes:

Your session ends automatically — no timer watching needed.

The comfort tends to stay with you well after the session ends.

It's simple, hands-free, and easy to make
part of your daily routine.

That's why most people who try it, keep using it.

The Truth About "Cheaper" Options


A $25 heating pad → Doesn't work → You buy 3 more things → 

Now you've spent $100+ with ZERO results


Weekly physical therapy → $150/session × 8 weeks = $1,200 

But you still need maintenance sessions which means more $$$


Ember™ → $139 one time → Works from day one → Use it forever


Which one actually makes sense?

"I spent $400 on other products before finding Ember.

Heating pads, ice wraps, massage guns, creams, pills, you name it I've tried it.

I was desperate and kept buying things that didn't work.

When I finally tried Ember, I was MAD at myself for not finding it sooner.

This should have been my FIRST purchase, not my last resort.

Don't make my mistake."

- David K., Verified Purchase


While you're here — there's something worth knowing.

Most People End Up Buying Two

Knee pain rarely travels alone. If your knees are hurting, chances are someone else in your household is dealing with the same thing


A spouse, a parent, a partner who watches you wince getting up from the couch and hasn't said anything yet


That's why we created our Buy One Get One offer:

One Ember: $139
One device. One person. Life-changing on its own


Buy One Get One: $149
Two devices. Two people. That's $249 in total savings versus buying each at full price.

We're not sure how long we can keep this offer running


But right now, for $10 more than the price of one, someone else in your life gets the same comfort you're about to feel


Most couples who order one end up ordering a second within a few weeks


The BOGO just skips that step — and saves you $249 in the process


🛡️ Both devices are covered by the same 60-day guarantee and 1-year warranty

"I Was Ready To Return It."

"I'm a skeptical person by nature. I'm 61 and I've tried everything.

So I told myself, I'll use this for 30 days and if it doesn't work, I'm sending it back immediately.

I meant it. I was READY to return it.

But after two weeks... I wasn't in discomfort anymore. 

I could play golf again. I was sleeping through the night.

Now that I have it, I've never even considered returning it.

I'm on month 5 now and I use it almost every single day.

Best purchase I made all year."

Common Questions About Ember

Some customers notice a difference quickly, while others find it becomes more noticeable with regular
use over a couple of weeks.

For best results we
recommend daily use for at least two weeks.

Every person is different — which is exactly why we offer
a 60-day guarantee.

You have two full months to
decide whether Ember is right for you.

We ship within 1-2 business days. Most customers receive their orders within 5-7 business days, depending on their location.

You'll receive a tracking number via email as soon as your order ships.

Your Ember device, a USB-C charging cable, and a user guide with instructions.

Yes — completely cordless and rechargeable via USB-C.

A full charge takes approximately 2 hours and powers several sessions per charge: no outlets, no cords, no restrictions on where you use it.

Yes. Ember fits both left and right knees and adjusts to fit most knee sizes comfortably via the adjustable straps.

Each session is 15 minutes. Ember has a built-in auto shut-off that ends the session automatically, so you never have to watch the clock.

Most people use it once or twice daily.

No. Ember is a wellness device designed for everyday comfort and temporary relief of minor aches and muscle tension.

It is not intended to diagnose, treat, cure, or prevent any disease or medical condition.

If you have a diagnosed knee condition, please consult your physician before use.

Ember is not recommended for people who are pregnant, have an implanted electronic device such as a pacemaker, have an active infection or open wound in the knee area, or have severe swelling.

Unlike a standard heating pad, Ember's TheraSync™ technology combines red light therapy at 615-650nm, infrared heat, vibration, and compression in the same cordless device.

Most standalone red light therapy devices at this wavelength sell for $200-400 separately. With Ember, it's all built in.

Many customers prefer that all-in-one routine over using separate products.

Yes. Every Ember device includes 14 red light diodes operating at 615-650nm — within the wavelength range studied in peer-reviewed photobiomodulation research for knee joint health.

Red light therapy works simultaneously with
infrared heat, vibration, and compression
during every 15-minute session.

Yes — through a simple reimbursement process with our partner Flex.

Here's how it works:

1. Complete a quick chat consultation with Flex to see if you qualify — no scheduling, no video required. Takes minutes.

2. If approved, you'll receive a Letter of Medical Necessity in under two hours.

3. Purchase Ember™ using any standard payment method — credit card, debit, or PayPal.

4. Submit your Letter of Medical Necessity and your Ember receipt to your HSA or FSA administrator for reimbursement.

Your Letter of Medical Necessity is valid for 12 months from the date of issue.

[Start Your Consultation →]

Ember offers three adjustable heat settings ranging from 45°C to 55°C — low, medium, and high — allowing you to customize the warmth level to your comfort preference.

The 15-minute auto shut-off applies to all heat settings.

Physical therapy: $150-200 per session, typically recommended 2-3x per week — that's $1,200-2,400 per month.

Standalone red light therapy devices at 615-650nm: $200-400 for a single-modality device without heat, vibration, or compression.

Prescription pain management: $8-12+ per day in ongoing costs, with side effects you don't get from Ember.

Ember is $139 once. No appointments. No refills. No recurring cost. And it combines four therapies that would cost significantly more to access separately.

Every day you wait is another day you don't have to be in pain.

"Why Did I Wait?"

"I watched this page for 3 weeks before ordering.

I kept thinking maybe I should wait for a better deal or maybe I don't really need it.

Looking back, I wasted 3 weeks of feeling better because I could've been using Ember this whole time instead of suffering.

Don't make my mistake. If your knees hurt, just try it. You have 60 days to decide anyway."
